Abstract

The present disclosure relates to a vortex chamber comprising a cavity elongating along a central axis and a swirl generator. The swirl generator comprises a plurality of swirl channels configured for introducing a gas flow into the cavity as a vortex flow about the central axis, each swirl channel comprising a channel entrance and a channel exit. The swirl generator further comprises a gas redistribution chamber comprising one or more main gas supply inlets for receiving a gas, a distribution channel configured for distributing the gas received from the one or more main gas supply inlets to the channel entrances of the swirl channels, and one or more blocking walls configured for blocking and unblocking one or more entrances of the plurality of swirl channels. The vortex chamber is further configured for relatively rotating the channel entrances of the swirl channels with respect to the one or more blocking walls from a first angular position to at least a second angular position and vice versa, and wherein when in the second angular position the one or more blocking walls block a larger number of channel entrances than when in the first angular position.
